Update as of Feb. 6:  This very popular model of Geiger counter, the Rad 100, is now back in stock, for immediate shipment.

---------------------------------------------------------------------------------------------------------------------------------

The recent stepchild to the Radalert 100X, and as in its parent model, the Rad 100 is designed for general purpose monitoring of radioactivity.

The Rad 100 is identical to the Radalert in most every respect.  The main difference is that the Rad 100 has no user adjustable audible Alert feature, making possible substantial savings to the consumer.

Like the Radalert 100, the Rad 100 otherwise offers these main features:  

  • Detects Alpha, Beta, Gamma and X-radiation
  • Digital readout on large, easy to read LCD display
  • Readings in CPM and mR/hr, or µSv/hr
  • Total mode for timed counts
  • Audible clicking with each radiation count detected (can turn off)
  • Data Port for connection to computer or data logger

The Rad 100 is an excellent value for the money, offering good sensitivity in a user friendly Geiger counter with digital readout.

This item typically ships within 1 business day.

Specifications for the Rad 100:  

Detector

Halogen-quenched, long thin cylindrical Geiger-Mueller tube (LND712)  with side wall of .012" #446 stainless steel, and with thin mica end window

Window Size

1.5 to 2.0 mg/cm² thick;

Radiation Detected Alpha, Beta, Gamma, X-ray
Sensitivity Detects alpha down to 2.5 MeV; efficiency at 3.6 MeV > 80%
  Detects beta at 50 keV w/35% efficiency, at 150 keV w/75%
  Detects gamma and X rays down to 10 keV thru window, 40 keV minimum through case; gamma sensitivity is 1,000 CPM/mR/hr     referenced to Cs-137
  Normal background is approximately 10 to 20 CPM
